These are made with velboa, faux fur, coral fleece, dimple velour, and fleece material. We have used an 11" x 5 3/4" piece and sewn it into a bag then stuffed it with a potent catnip and some Eco friendly fiberfill. Your kitty will rub against them, drool on them, lick them and kick them with their hind feet. No colour choice as there are too many to chose from! These are also washable/dryable.
